Refuelling

Refuelling

Risk of explosion

Fuel is highly flammable. Fire, naked flames and smoking are therefore prohibited when handling fuels.

Switch off the engine and the auxiliary heating* before refuelling.

Risk of injury

Avoid any contact with fuels.

You can damage your health if your skin comes into direct contact with fuel or if you inhale the vapours.

Do not use diesel to refuel vehicles with a petrol engine. Even small amounts of diesel will damage the injection system. Damage caused by using diesel to refuel vehicles with a petrol engine or mixing petrol with diesel is not covered by the warranty.

Do not start the engine if you accidentally refuel with the wrong fuel. Otherwise, the fuel could enter the fuel lines. The fuel tank and fuel lines would then have to be drained. In this case, notify a qualified specialist workshop and have the fuel tank and fuel lines drained completely.

When you open or close the vehicle with the key or KEYLESS GO*, the fuel filler flap is automatically unlocked or locked.

Petrol (EN 228)

Refuel using only unleaded premium grade petrol with a minimum octane number of 95 RON/85 MON conforming to European standard EN 228.

You could otherwise impair engine output or damage the engine.

You will find further information about petrol under "Fuel" in the index.

As a temporary measure, but only when the recommended fuel is not available, you may also use regular unleaded petrol, 91 RON/82.5 MON. This may reduce performance and increase petrol consumption. Avoid driving at full throttle.

In some countries, the available petrol quality may not be sufficient and could cause coking around the inlet valve. In such cases, and in consultation with a Mercedes-Benz Service Centre, the petrol may be mixed with the additive recommended by Mercedes-Benz (part no. A000989254510). You must observe the notes and mixing ratios given on the container.

AMG vehicles and twelve-cylinder engines

Refuel using only super unleaded petrol with a minimum octane number of 98 RON/88 MON conforming to European standard EN 228.

You could otherwise impair engine output or damage the engine.

You will find further information about petrol under "Technical data" in the index.

If the recommended fuel is not available and only as a temporary measure, you may also use premium unleaded petrol, 95 RON/85 MON. This may reduce performance and increase petrol consumption. You must avoid driving at full throttle.

In emergencies, and only when the recommended fuel is not available, you may also use standard unleaded petrol, 91 RON/82.5 MON. However, using this fuel results in considerably higher petrol consumption and significantly reduced performance. Avoid driving at full throttle, and only drive in drive program C.

If no fuel other than regular petrol fuel 91 RON/82.5 MON or a lower grade is permanently available, you should have the vehicle adapted to run on this fuel by the local after-sales service.
